Anything LiveCode Can Learn From GO

I was referring to a local mobile SQLite DB query. But I do use async tsNet for web service requests. It works like a charm even with many requests outstanding. I fire up 10 or more at a time and they all compete as expected. Async tsNet +1

tsNet with async calls can help you get this.

Say you were going to a new card that required a DB query. You could have the card layout code and the query to a local DB running at the same time. Even with LCs message hierarchy multithreading could work. You could fire off a DB query thread and have a message sent to the main thread when complete. Inter thread communication would be key. That is where locking would be tricky to prevent dead locks.

But the real problem comes with concurrent execution, threading-locking, race conditions and deadlocks. Those things make it hard to create a multi-threading application on those languages.
